WINDOW-WASHERS SEAT.

Application Med Julie 21, 1927. Serial No. 200,337.

orm that saidplatform, 0r Seat, may be.

placed upon the ledge of any window and its clamp means readily adjustedto the window sill to clamp the platform in position in the window frameto provide a safe means upon which the Window Washer may stand, or beseated, duringhthe time 'he is washing the windows or t e outside of thebuildarious safety'appliances have been provided for the security ofwindow washers, but none of these, lto my knowledge have utilized theprinciples involved in my present construction.

The primary object of my invention is to provide a safe, strong, andreliable seat, or platform, of the character designated that may beeasily and qulckly placed on any window ledge and clamped thereto toprovide a safe seat, or platform, forthe use of window washers inwashing the outside windows of buildin s.

Another object o the invention is to provide a seat ot theclass*designated that embodies in its construction a simple and readilyadjustable clamping means adapting 1t to be rigidly clamped in positionto the sill of a window.

Other ob'ects and advantages of my invention will be apparent withreference to the subjoined specification and 'accompanying one sheet ofdrawings in which:

Figure 1 is a plan view of my improved window washers seat, showing thereferred construction embodying the princip es of my invention;

Figure 2 is a side elevation of the seat, showlng it mounted 4upon theledge of a window, with its clamp means adjusted to the sill thereof;

Figure 3 is a frontelevation tion, the section being indicate 3-3, inFigure 1; and

Figure 4 is an enlarged sectional detail of one of the clamps and itsadjusting screw., the section being indicated by the line 4 4, in Figure1.

Referring more specifically to the draw partly in secby the line ings,the frame 5 preferably consists of a rectangular piece of wood, havingprovided on its under surface a pair of spaced angieiron braces 6 and 6bolted thereto by a plurality of bolts 7 and 7. i

A pair of supports 8 and 8 are disposed edgewise under the frame orplatform 5, and abut against the inner faces of the braces 6 and 6',with stiifenin bars 9 and 9 disposed against the inner aces of saidsupports 8 and 8'-, said braces 6 and 6 and bars 9 and 9', embracing thesaid sup orts 8 and 8', the several parts being rigidlylirolt- `edtogether by rows of bolts 10 and 10 The' braces 6 and 6 extend slightlybeyond the front edge of the platform 5 and embrace a transverseclamp-supporting member 11, the member 11 being provided with dependinglugs 12 and' l2 adapted to. fit between the extremities of the braces 6and 6 and the bars 9 and 9 to which said lugs are rigidly bolted.

A pairvof bosses 13 and 13 are integrally formed with theclamp-supporting member and are positioned immediatel adjacent the lugs12 and 12 thereof, sai bosses beingprovided with tapped openings 14 and14 adapted to receive the adjusting screws '15'V and 15, as hereinafterdescribed.

The front ends of the supports 8 and l8 are of considerably less depththan the rear ends, as clearly shown in Figure 2, the under forwardedges thereof 16 and 16 being bevelled or tapered rearwardly throughoutmore than half their lengt-hs, so that said supports wiil rest upon andadaptthemselves to the slant of any ordinary window sash, as indicatedby the dot-and-dash lines in Figure 2.

When the seat, or platform, 5 is positioned upon the window sash, asshown in Figure 2, the upper face thereof is substantially level and theWindow washer may sit or stand thereon While washing the outside throughwhich loosely mounted handles 19 and 19 extend.

Sill-engaging hooks, or clamps,20 and 20' p l are mounted upon thebearing sections 17 and 17 of the adjustin screws, and consist of bosses21 and 21 avin openings 22 and 22 adapted to loosely t the sections 17and 17 of the adjusting screws shank sections 22, and inwardlyprojecting lugs 24 and 24 adapted to engage under the window sill asclearly shown in Figure 2.

lt is obvious that when the seat is placed upon the window sash, asshown in Figure 2, with the sill engaging hooks 20 and 20 engaging thesill, and the handles 19 and 19 are rotated, the hooks 20 and 20 willclamp the sill and draw the platform upwardl toward the rear edge tereof until the ront end of the platform is wedged tightly thereagainst,from which position it will be imossible to accidentally dislodge theplatorm from the sash. The window washer may be seated upon the(platform in the position ordinarl assume when sitting upon the sash,with is limbs extending into the room, or he may stand upon the platformand work in standing position, with a much greater degree of safety thanis possible with the usual make-shift appliances.

Having thus described my invention, I claim' and desire to secure byLetters Patent: f

In a window washers seat comprising a rectangular frame consisting of aseat portion, a pair of spaced sup orts mounted under said seat portionan having their lower edges bevelled at an angular inclination relativeto said seat portion, spaced bosses carried by. said frame, adjustingscrews mounted in said bosses and projecting outwardly from the frameand having heads formed at their outer ends providing shoulders, means'carried by the outer ends of said screws for causingr their adjustmentin said bosses, and loose y mounted clamp members carried by said screwsand abutting against said shoulders and adapted for adjustment relativeto said frame.

In testimony whereof l have'axed my signature.

S IMOV.
